Fabrication of localizing template for extraoral implant in a patient with congenital defect in one ear

Abstract

Introduction: The use of osseointegrated extraoral implants for retention of extraoral prostheses, such as ears offers ideal support and retention, and improves patient′s appearance and quality of life. However, the best result may be obtained only by careful planning number, position and orientation of the implants and this article presents a method of making of a surgical stent that is simple, economic and stable during all phases of surgery. Case Report: A 26-year-old male (without any remarkable systemic disorder) presented with congenital defect in one ear. An impression was made of congenital defect in left ear, wax pattern of defect and missing ear is made, the wax prosthesis is changed into a clear acrylic resin, and on the other hand an occlusal maxillary splint is also fabricated with clear acrylic resin. The occlusal splint and the acrylic resin ear are joined together using an extraoral bar that is made of proper length of wax and also is checked on patient′s face and processed into a clear acrylic resin. Discussion: By this kind of surgical guide, we can determine the best location of the implants and location of the implants will not compromise to fabricate ear prostheses with ideal form and location. This surgical guide can be used for the pretreatment of radiographic stent.
